Buying extra batteries for my Ibook.

[Dane Trethowan]

Hi!

I'm considering purchasing a few extra batteries for my Ibook machine  
but I have a question.  On all the mobile phones I've had, I've been  
able to purchase a desktop charger which has allowed me to charge any  
extra batteries I have so I can be sure that they're "ready to go" at  
a moments notice, can desktop charging devices or anything similar be  
obtained so that spare batteries can be charged?

Also, I'm wondering about bluetooth devices such as bluetooth  
keyboards, are they difficult to get going with the Ibook? Does the  
Ibook just detect them as it did with my bluetooth enabled mobile  
phone? Can bluetooth headphones be used etc?

thanks
